Factor the original expression using ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right). Substitute -1 for x_{1} and -1 for x_{2}.

Identify like terms in the expression. Add or subtract the coefficients of like terms. Rewrite the expression with combined terms. Simplify 4x+5−2x+3. Combine the like terms (4x and −2x): 4x−2x=2x. Combine constants (5 and 3; 5 + 3 = 8).
